Ultra-light inflatable sleeping pad from Flextail for trekking and winter overnights, offering top-class R-value 6.0 insulation, comfort down to -18 °C and a mummy shape to save weight and retain heat better. Thanks to a thickness of about 10 cm, U-shaped chambers and durable 20D Ripstop Nylon with TPU, it provides stable, comfortable sleep on uneven terrain all year round.
The Flextail Zero Mattress R05 Mummy L is designed for demanding outdoor expeditions where every gram counts, yet you still need reliable warmth and comfort. The high R-value 6.0 effectively reduces heat loss to the ground, making it suitable even for sleeping on snow and in cold seasons. The mummy cut reduces unnecessary surface area, helps keep warmth closer to the body, and also saves space in your pack.
The construction with U-shaped air chambers distributes weight evenly and ensures stable support when changing positions during sleep. The pad is also equipped with a one-way TPU valve, which speeds up inflation and makes deflation easier without backflow.
